Patented May 3, 1932 UNITED STATES PATENT OFFICE STANISLAV HACKENBERG OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE-HALF TO NAFANAIEL HACKENBERG, OF SAN FRANCISCO, CALIFORNIA TURBINE AND ATTACHMENT THEREFOR Application filed June 21,

The present invention relates to improvements in turbines and attachments therefor, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide a turbine which may be operated by a medium of relatively low pressure for actuating various attachments, such as burnishing tools, dental drills, egg heaters, or the like. The device is self contained and may be readily attached to a conventional faucet for making use of the pressure medium therein.

A further object is to provide a turbine which is simple in construction, durable and eflicient for the purpose intended. The various structural features of the turbine are simplified in such a manner that the same may be cheaply manufactured, easily manipulated, and readily prepared for operation.

Other objects and advantages will appear as the specification proceeds, and the novel features of my invention will be pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming a part of this application, in which:

Figure 1 is a front view of my turbine, parts thereof being broken away in order to expose the interior construction,

Figure 2 is a vertical transverse section through the central portion of Figure 5,

Figure 3 is an exterior view'of my turbine showing a burnishing tool attached thereto,

{{igure 4 is a partial plan view of Figure 5, an

Figure 5 shows a clamp which I employ.

In carrying my invention into practice, I provide a turbine generally indicated at 1 that is adapted to be secured to a conventional faucet 2, or other suitable pressure carrying means, and having means incorporated therein for actuating a driving element 3 which is connected to any desirable attachment whereby the latter may be 0perated. The faucet 2 mav be connected to any source of pressure, and the agent causing the pressure may be presented in either a fluid or an aeriform state.

The turbine 1 consists in its structural fea- 1930. Serial No. 462,850;

tures of a central supporting plate 4 having cylindrical housings 4 and 5 secured to the opposite sides thereof by means of screws 6, or other suitable fastening means. The housing 4 has a conduit 7 extending substantially diametrically thereacross, the upper end of the conduit having an internally threaded coupling 8 rotatably secured thereto and adapted to be threaded onto the faucet 2.

A rotor 9 is mounted in the housing 4 and is secured to a shaft 10 that extends through bearings 11 and 12 in the plate 4 and housing 5 respectively. The rotor is fashioned from a ring-shaped disc 13 and a plate 13 having blades 14 secured therebetween which are arranged at an angle with respect to the radii of the circle as clearly shown in Figure 1. An arc-shaped member 15 projects inwardly of the housing 4, and this member is slightly spaced from the inner edge 16 of the disc 13, see Figure 1.

The fluid or aeriform medium that enters the conduit 7 is conveyed through a nozzle 17 and is discharged through an aperture 18 in the member 15 against the blades 14 so as to impart rotary motion to the rotor. The nozzle 17 is arranged at slightly more than a right angle with respect to the plane of the blades 14 in order that the medium may be discharged against the blades with the maximum mechanical advantages, and at the same time the medium will be deflected through an. opening 18' formed in the wall of the housing 4. The member 15 prevents the medium. if the same be a fluid, from splashing from the blades into the interior of the housing 4. The course of the medium is accordingly directed downwardly through the opening 18 where it enters a discharge pipe 19. the flow of the medium in the latter being co trolled by a valve 20.

Referring more particularly to Figure 2, it will be noted that the valve 20 is carried on a shaft 21, the latter extending through a packing gland 22 and terminating in a crank 22'.

The shaft 10 extends entirely through the Wall 23 of the housing 5 and is slotted at 24 for receiving one end of a flexible drive 25 of convent onal design having a flexible wire t-herein. This direct drive from the shaft 10 to the flexible drive is what I term the low speed of the turbine.

The shaft 10 is also provided with a pinion 29 that meshes with a large gear 30 which is carried by a shaft 31. The housing encloses both the pinion and the gear so as toprovide an oil reservoir; The shaft 31 extends through the wall 23 of thehousing and has a pulley 32 mounted thereon wh ch may be used as a low speed drive. I 7 'From the foregoing description of the various parts of the device, the operation there of may be readily understood. The pressure medium entering the conduit 7'is conveyed through the V nozzle 17 and is discharged therefrom so as to rotate the rotor 9. This motion is transferred through the shaft '10 to the flexible wire (not shown) of the drive 26.

v If .a lower speedof rotation is desired, the

drive may be directly connected to the shaft 31. 7

As previously stated, my turbine is capable of actuating a burnishing tool or the like.

, Thistool is indicated in Figure 3 by the numoral 50. The shaft 51 thereof is connected to the flexible drive 25 in any suitable manher.) The shaft 51 is supported at substantially right angles to the plates of the turbine bya clamp 52 of the shape shown in Figure .5.

' and a V-shaped member 59. .As this latter member is moved toward the bracket 54, the

flexible conduit is forced into grooves 60 in the bracket so as to support the burnishing tool. at the desired angle. we
